Hi Hims, May be my question was missunderstood. According to Delphix documentation "Delphix Agile Data Masking extracts the data from a source environment, such as a production copy, gold copy, or disaster recovery copy (only read from a database not an archived file)". So the question is regarding database archive files, how the masking engine integrates there contents to a masked database in both on-the-flyer and in-place options if there any difference. Hope my question is more clear now. Regards, MSA
